A7-500 Crossover Recommendations?

[LowOhms]

Hi Louder,

I personally would NOT be so quick to get rid of the one inch EMILAR EA-175s.

The main thing in 2017 I worry about is that their Alnico magnets may not be fully charged. Elitopus 1 runs them, switches between them and ALTECs I think, and likes them, as do people like Joe Roberts, and Joseph Esmilla, both good listeners.

I DO think non stock Woofer recones can be quite suspect, but for now.... initially, yer " Run What 'Ya Brung" is pretty good advice !!

When I buy a used ALTECs ( bought Valencias and 19s this year ) I figure, all the drivers will get gone over by GPA, re magged, etc.

FV says he will email me....cool.

Thanks Jeff and all for your detailed responses.

Since I was a new poster on Hostboard, this took a few days to appear, so I was surprised to see all the thread action.

These speakers will only likely live in my studio at work. They'll never cross the threshold at home (unless my wife decides to run off with the mailman!) My studio is fairly large at 22x60x18' high. Brick walls, wood floors, glass window wall, wood ceilings, city noises. So a lot to deal with (it was part of an old disco). The good part is that we're surrounded by a parking garage, so no neighbors to complain when things are cranked up!

I was wondering if it's worth trying to get an old Altec crossover with brightness knob (like a N801-8A) and gut it and rebuild the caps. I like the look of the Altec crossover plates/knobs. Is there a particular model that is suited to doing this?

Or just build one from the ground up. Would you recommend having an L-pad in the HF section as Altec did or just go with a single resistor (or none)?

Your idea of weighting the top is interesting. I'm wondering if I use sandbags, and then place the horns on top of the bags would kill two birds with one stone?

I'll be in touch with a PM...

Hi FV,



I have been eating, dreaming, thinking and breathing A7-800s for home-use for a few years now, as I SLOWLY, on a budget, have been setting mine up.

Been going to RMAF audio shows, last ten years in a row, and for three days straight, hear possibly the world's finest ALTEC 604 system at this Denver show, source, certainly the amps, and MLTL speakers, although results do vary some, from year to year. ( Lack of set-up time. )


I would PASS on re-doing an ALTEC " 800 " series crossover. Waste of money, from my direct 2017 experience. I have actually just DONE this, for a fellow in Switzerland, and posted photos on this Forum.

For DIY passive crossovers, I know of GREAT parts and things to use, for PENNIES on the dollar, that sonically will far-outperform "conventional audiophile-parts implementations" which a majority of audio people tend to pursue.

Go slow. No mistakes. Please contact me and we will talk, which beats typing things out.

So glad you have a McIntosh 60 pair of monos !!!!! That will EASILY be adequate, when we are done with it all. COOL.
